I didn't find the oil change interval in my owners manual. It refers to the maintenance minder in the dash but how many miles do they recommend between oil and filter changes? I now have 600 miles on the car. Thanks for your information. Central Oregon

We went at 3k miles and the service manager told us since the oil life meter on the CT read only 50% we should come back when it reaches 15%. On these cars its no so much the miles anymore but the oil life it self.

The Honda engineers must be making some incredible engines. Was concerned on the recommended oil 0-20wt. Yikes that's thin! Seems Ok for winter but what about summer? Went on the Honda website and I see that their oil is over $14.00 qt.. I couldn't find anywhere if it's full synthetic or a synthetic blend. Does anyone know? Seems like that cost is reasonable if you only have to change once a year. I see that this oil seems to help mileage. Less fluid resistance in engine? We sure are enjoying the CT. It's really quiet and not as much road noise from the tires as Hondas we've owned in the past. That was the only problem I had with Honda was the road noise. Getting better and better. Will continue to purchase Honda and Toyota as I'm thinking that nearly all of their parts are not made in china. I see where Government Motors are Manufacturing their car parts in China and shipping them here to the U.S and assembling them. Maybe for import duty advantage? Well the Japanese ate our lunch when they brought their cars here and showed their quality compared to the U.S. built cars and now the Koreans are going to do the same thing. When will the U.S. manufacturers learn??

Go by the oil minder on the dash. The wrench light and type of service required will be displayed on the dash when it is time.

Instead of judging only by miles driven, the maintenance system in the car calculates oil change intervals by not only miles driven, but total RPMs maximum RPMs, idle times, etc.

It's a much more "accurate" way to determine when a change is needed.

(This is of course aside from the initial break-in procedure for a new CT, which is outlined in the owner's manual.)

So the type of oil one uses (dino / synthetic) never comes into play? In all of my cars I run Mobile1 and normally change the oil between 8,000 and 10,000 miles. But if the CT will decide regardless of oil type then I need to rethink this as I am ok paying more for synthetic because I can run it longer...

Correct, the maintenance minder system in the CT does it's calculations based on the use of the recommended 0 weight oil.

(As far as I know) There is no way to stipulate another weight oil in the carputer.

When I took my CT in for an oil change I asked whether they used full synthetic or synthetic blend. I was told that the car comes from the factory with a synthetic blend. They charge $49 for an oil change with the synthetic blend, and $69 for full synthetic.
